Senior Romney campaign adviser Eric Fehrnstrom said today that the former Massachusetts governor has no plans to release additional tax return information, even as a new report shows the wealthy candidate has obfuscated his finances by taking advantage of an “obscure exception in federal ethics laws.”

Appearing on MSNBC this morning, Fehrnstrom said Romney has been forthcoming and complied with all laws. “So, definitely no plans on releasing any more tax returns?” host Chuck Todd pressed. Fehrnstrom reiterated what the campaign has already released, saying, “we think that’s sufficient.” Watch it:

So far, Romney has released only his full 2010 tax returns and an estimate of his 2011 return, and Fehrnstrom said Romney would disclose the full 2011 return once it’s filed. But this is fairly meager compared to other presidential candidates, who often release multiple years of returns. Indeed, Romney’s own father released 12 years of tax returns when he ran for president.

As the Washington Post reported, Romney’s existing returns hide much of what Romney is actually invested in by listing only the funds he owns, not their underlying investments.

Romney’s 2010 returns showed he made over $20 million that year and had offshore accounts in Switzerland, Luxembourg, and the Cayman Islands, and some have speculated that Romney is refusing to release returns from previous years because they might have additional embarrassing information.
